Title: Polyolefin porous membrane made hydrophilic and its manufacture
Inventor: ITO HAJIME
IPC: B01D71/06
Filed: 1984-09-12
Abstract: PURPOSE:To obtain the titled polyolefin porous membrane useful as a permeable membrane, an ultrafilter membrane, etc. and without losing its hydrophilicity when temporarily dried by forming an ion complex of a quaternary ammonium salt and an acidic polysaccharide on the surface of a finely pored membrane. CONSTITUTION:A polyolefin porous membrane is immersed in a >=0.1% aq. soln. of a quaternary ammonium salt (e.g., cetyltrimethylammonium chloride) having a >=6C hydrocarbonic group, and then immersed in a 0.1-5% aq. soln. of an acidic polysaccaride (e.g., carrageenan and heparin). The quaternary ammonium salt and the acidic polysaccaride form an ion complex, and are insolubilized and deposited on the membrane. Since the ion complex has sufficient hydrophilicity, the membrane thus treated is capable of permeating water under low pressure even after being dried temporarily, and the water permeation velocity is not deteriorated as compared with the membrane which is made hydrophilic by alcohol.
